Rickie Fowler was rated as one of the fastest players on Tour.

How do you measure how fast (or slow) Tour players hit their shots? You need a stopwatch, a clipboard and lots of sunscreen.

I was part of a team of four Golf Magazine editors who spent Friday at the Arnold Palmer Invitational in Orlando to time players for the magazine's special report on slow play. To get this data, we timed every shot hit by 45 players over nine holes in the second round on Friday in Orlando. Our day started with the first groups at 7 a.m. and ended at 6:30 p.m. as the final groups finished their rounds. I ended up with sore feet, a ruined pair of Nikes and a watermelon-colored sunburn on my calves despite liberal sunscreen application, but I also had some pretty extensive data on how long Tour players took over their shots.

Some Disclaimers: We started the clock only when a player had arrived at his ball and it was his turn to hit. As far as choosing groups to follow, we selected most of them based on tee times (we wanted to record as many players as possible). However, we also made a point to follow players known as slow (like Kevin Na) or fast (like Rickie Fowler). Yes, this is just a snapshot of 45 Tour players on one day, but we recorded 1,497 shots and this data is an accurate representation of pace of play on today's PGA Tour.

Here are some highlights from our data:

The Five Slowest Players

1. Nick O'Hearn
Average Time Per Shot: 55 seconds

2. J.B. Holmes
Average Time Per Shot: 52 seconds

3. John Senden

5. Cameron Beckman

Average Time per Tee Shot for Field: 31 seconds

Average Time per Putt for the Field: 37 seconds

Most Time Over a Single Tee Shot: Hunter Haas (119 seconds, par-3 second hole)

Most Time Over a Single Putt: Kevin Na (91 seconds, 9-foot, 11-inch putt for birdie on par-15 12th hole; he missed)

We gave this data, as well as similar data on amateur shots, to Golf Magazine Top 100 Teacher and CBS Sports analyst Peter Kostis. Peter's take: Tour players take more time on shots as they get closer to the hole, but you take less time with each shot.
